This invention relates to time controlled annunciators, and same has forits principal object to provide an annunciator which may be very easilycombined with the essential working parts of an alarm clock and whichwill include a decidedly novel setting mechanism and means co-operabletherewith for causing the alarm to sound either at a singlepredetermined time or periodically and at diiferent predetermined' l0times as may depend upon the use to which the annunciator is put.

The annunciator is primarily, but not necessarily, designed for use forthe purpose of reminding one that a particular time of the day hasappreached for the tuning of a radio receiver for the reception of aparticular program which is to be broadcast from a certain sendingstation. I am more or less familiar with various well known types ofstation tuning mechanisms for use in connection with radio receivinginstruments and that they have had for their purpose the automatictuning of the receiver at a predetermined time. Such automatic stationselectors or tuners have not proven entirely practical for more than onereason. They are usually complicated; not always entirely reliable andare somewhat costly and diiicult of operation. In view thereof, I havedesigned an instrument whose cost should not much exceed that of anordinary alarm clock, one which is of light weight and freely portableand which may be used to satisfy all of the ordinary purposes of analarm clock, thus enabling the instrument to be employed in this highlydistinctive dual capacity. I have further constructed the instrument sothat use thereof shall not require that it be incorporated in areceiving set or connected with any of the working parts of said set.

A very important object of my invention is directed to a novel alarmsetting mechanism whose design makes possible an almost unlimited rangeor" time adjustments, whereby the alarm may be made to sound on thehour; or at fifteen, thirty or forty-five minutes thereafter, or attimes separated from each other by fifteen minute intervals between anytwo consecutive hour indications upon the dial of the instrument.

@ther new and novel features of the invention will suggest themselves tothose skilled in the art upon reference to the accompanying drawings, inwhich Figure 1 is a view in front elevation of the annunciator;

In Figures 1 and 2 of the drawings is illusti'ated a clock casing IS, atthe front of which is an hour dial Il through the center of which passesan hour hand arbor I2. The said dial is provided with an outer portionI3 formed with 35 twenty-four radial slots I4. These slots areequi-distantly` spaced apart from each other and the alternate ones arealined with the respective hour markings H on said dial, and the othersare positioned just midway between the said hour markings. These slotsopen at their outer ends onto the peripheral edge of said dial and lyingin a position parallel to each slot is a friction inducing spring I5.Mounted to slide in each of the slots is an elongated 45 predeterminingelement I6, the transverse shape of which is circular as shown in Figure4. These elements are formed at their sides with longitudinal grooves l1in which the edge Walls of the slots Iii are received, whereby the ele-50 ments IS can be moved radially of the dial. The springs I5 arethreaded through the mating elements IS and same coact with the adjacentgrooves Il to yieldingly bear against the walls thereof to inducesufcient friction between the elements and the springs to cause saidelements to be retained in their selected positions of radial adjustmentin the slots I4. Midway of its ends, each of said elements IB is formedwith a kerf or marking I8 and same is adapted to or marking I9 on theVdial.

coincide with a concentrically positioned band It will be noted that theelements I6 are of short length With respect Vto the length of the slotsi4 so'that they may each be moved to any one of several possiblepositions on the dial, as will be appreciated upon reference to Figure lof the drawmgs.

In back of the dial Il and Ysecured in a fixed position on the arbor l2is a large pinion 20 Which meshes With a small driven pinion 2|,V

the latter constituting a part of a clock mechanism to be describedlater. The pinion20 is accommodated in the slot 22 in a plate or head23, the latter flanged at 24 within the annular walls of the casing l asshown in Figures 5 and 6. The arbor carries a fixed radial arm 25 ofresilient material, at one side of which is a power transferring member26, the same hinged at 2 to said arm 25 so that it can move laterallywith respect to the inner face ofthe dial il. The hour hand arbor isformed with an axial bore 28 in which a pin 29 is mounted for limitedsliding movement. Positioned in back of the pin is the angular branch 36of an oscillating shaft 3l, the latter being operatively mounted on saidarm 25. The shaft is also formed with an angular branch 32 and same isconstantly disposed in the path of movement of the member 26. It is inthis manner that the pin 29 is adapted to be projected to the positionshown in Figure 6 and to normally occupy the position shown in Figure 5.A leaf spring 33 is carried by the member 25 and same yieldingly bearsagainst the rear face of the member 26 so as to normally urge the latterin the direction toward the inner face of the dial H. The member 25 isformed at its outer end with an angular slotted portion or guide flange3d through which passes the reduced end 35 of the aforestated member 26,and, as illustrated, said end 35 is provided with a pair of conicalstuds 35 and 3l which face towards the back of the dial l l. The studsare staggered With respect to each other and they occupy positionsrelatively to the circle or marking i9 on the dial l l so as to movealong annular paths which are concentric thereto and to be interceptedor obstructed by some of the elements i6 and to coact cam-like therewithduring rotation of the hour hand H1. This causes motion to be set up inthe rocking shaft 3| and in turn utilized to partly project the pin 29from the bore 2B in the hour hand arbor l2. In the description tofollow, I shall refer to the stud 36 as the outer stud and Vthe one 37the inner stud. Substantially all of the parts so flange 34 formed witha smooth faced foot 38 'which is adapted to readily ride against theinner flat face of the aforementioned head or plate 23 during rotationof the hour hand arbor.

On a driven shaft 40 is mounted the aforesaid small pinion 2| as shownin Figure 2. This shaft is adapted to be driven through a gear trainWhich includes the driving gear Ma as shown in Figures 9 and 10. Exceptas herein specifically referred to, I of course make no claim to theclock Works per se. I shall'therefore describe those parts thereof thatmay be deemed 5 necessary to enable a person skilled in the art tounderstand and practice the invention. Y On the center wheel shaft 32 isa cam 43 the same adapted to make one revolution in each hour. Thisshaft has a gear pinion il@ Which meshes 10 with a minute Wheel 65.(Figures 9 and 10), the latter meshing with a small gear pinion i6 onthe shaft 61 kof the minutes indicator 48, the pinions il@ and 36 eachhaving the samenum- .ber of teeth. The clock frame i9 upon Which 15 theshaft 6l is mounted to revolve is provided with a dial 5t, thelatterpositioned in back of a transparent panel 5i mounted in the Walls of thecasing l, as shown in Figure '7. The U shaft fil passes through saiddial and same has go xed thereto a minute hand 52. This hand is situatedbehind the panel 5! and same is adapted to coact With the minutemarkings on the Vscale'of said dial. At this point it should be notedthat the scale of the dial 56 is divided 25 into a number of timeindicating divisions which exactly coincide with the number of pos--sible time adjustments of the respective elements i6 on the dial Il.When the hand 52 shall have made one complete revolution aboutgo itsdial 56, the hour hand I-I1 will haveftraveled one-twelfth its distanceabout the dial H. VBecause of the means herein employed Vfor driving theso-called minutes hand 52, it follows that the action of this hand isoperatively syn- 35 chronized with that of the said hour hand H. Withthe matter just preceding in mind and on reference particularly toFigures 9, l0 and 11 of the drawings, it will now be noted that the faforesaid cam i3 on the hour hand arbor 42 is 0 formed with fouridentically constructed radial lobes which are separated from each otherby substantially V-shaped notches 54. Each of these lobes is formed witha smooth peripheral surface Whose function and that of each the notches54 will be described presently.

Mounted to rock as a unit on the stub shaft 5B of the frame 56 is alever assembly 57, consisting of arms 58, 67, 68 and 69,all of which areintended -v to rock as a unit. The arm 58 is formed with a shoulder 59against which a pin 66 on the long arm 6i of a rocker 62 is adapted toengage when the parts occupy the relative positions shownV in Figure 11.This rocker is pivoted to the frame y 49 at 63, and at a point belowsaid pivot, said 55 rocker has attached thereto one end of a coil spring64. The opposite end of this spring is connected with the frame i9 andit thus follows that by the action of said springthe rocker willbe urgedin the direction of the arrow (a) in 60 Figure ll, the moment the pin 66is free from said shoulder 5S. Said rocker is formed with an arcuateslot in which a stop pin 65 on the frame Il@ passes. As previouslystated, the lever assembly 5l also includes the arms 6l, 68 and 69, 65the latter having a foot 76 adapted, when the lever assembly tilts underthe Yaction of the spring 5M, and to the position'shown in Figure 10, tocontact with the latching stub 'H on the oscillatory member l2. Themember 'l2 extends 70 from an oscillatory spring tensioned shaft 73, theends of Which are mounted to turn freely in the respective side platesof the frame @9. The spring 73a (Figure l2) of the shaft 'i3 functionsto urge the member 12 in the direction of the 75 arrow (b) in Figure 9.From said shaft 13 extends a latch arm 14, the free extremity of whichis formed with an angular branch 15. Upon reference to Figure 9 of thedrawings, it will be noted that when the lever assembly occupies theposition therein illustrated, the branch 15 of the arm 14 engages in thenotch 16 in the peripheral edge of a disk 11 which latter constitutes apart of a spring actuated hammer operating means 13, (Figure 14) thesaid disk being carried by a sleeve 11a which is free to rotate on theshaft 19, said sleeve having secured thereto a gear 11b. The gear 11b isadapted to be driven by the spring through the escapement element 81(Figure 13) co-acting with the escapement wheel 88 of the means 18. Theaforementioned latching stub 1| of the oscillating member 12 is adaptedto engage in the notch 8| in the end portion 82 of the vibratory hammerarm 83, the hammer 34 of which is correlated to the bell 85 so as tooperate thereagainst as would be the ordinary action of like parts inthe customary operation of any well known form of alarm clock. It willdoubtless sufce to say that the arm 83 is Xed to an oscillatory shaft 36and that the latter is provided with the escapement element 81 whichcoacts with the aforementioned escapement wheel 88 of the means 13. Fromwhat has been stated, an alarm releasing actuation set up in the shaft13 will cause the stub 1| to be withdrawn from the notch 8|. This willbe followed by an immediate release of the branch 15 from the notch 16in the disk 11 and the member 12 will be then acted upon by peripheralengagement with the disk until the latter shall have made one completerevolution, at which time, the stub 1| will again enter the notch 8| andthus shut off the alarm mechanism.

The arm 61 is adapted to coact with a latch member 89, the same pivotedat 9|] to the frame 49, and normally urged to the position shown inFigure 5 by the spring |98. Said member is formed with a hook 9| and alug 92, the latter spaced apart from the shoulder 93 of the aforesaidhook so that when the member occupies the position shown in Figure 5,the free end of the lug will bear against the offset free end 94 of aleaf spring 95. The spring 95 is secured at 96 to the head 23 and sametraverses the open end of the bore of the hour hand arbor where it willbe forced to the position shown in Figure 6 against the normal action ofthe spring |98 when the pin 29 is projected in response toan action setup in the power transferring member 26, such as when one or the other ofthe cone shaped studs 36 or 31 is acted upon a by a previously setelement I6, see Figure 6. The arm 68 is formed with a cam face 91 and onreference to Figure 10, it will be seen that same is adapted to freelyenter any one of the spaces 54 between the adjacent lobes 53, at whichtime the inner face of the arm 61 will come closely against the shoulder93. When, however, the peripheral face of any one of the lobes is incontact with the edge portion 91 of said arm 88, there will exist aclearance between the shoulder 93 of the latch member 89 and the inneredge portion of said arm, the purpose of which will be explained in thedescription of the operation of the invention to follow.

The pin 69 on the arm 6| is adapted, when the lever assembly 51 is inthe position shown in Figure 10, to engage in the recess 99 in the arm58 and to ride over the cam face |69 during the return of the arm 62 tothe position shown in Figure l1. On the rear face of the disk 11 is apin and during rotation of said disk in the direction of the arrow inFigure 10, said pin will engage with an arm |92 of a rock shaft |33, thelatter having a lug |84 in the arcuate path of movement of which isdisposed a stop |95. This shaft |83 is formed with an actuating lug |96,the spring 64 tending to present the cam edge |81 to said lug. Itfollows that when the disk 11 moves in a counterclockwise direction, thepin |9| will coact with the arm |92 and thus urge the lug against theface |91, and, in turn, rock the arm 62 against the action of the spring|59. This causes the pin 85 to bear against the face |30 of the lever 58and to ride thereover and to finally fall behind the shoulder 59,whereby to sufciently tilt the lever assembly. to raise the foot 18 awayfrom the lug 1|, at which time the several coordinated mechanisms willhave assumed their normal positions.

In Figure l of the drawings the element i6 between the hours of twelveand one has been adjusted to a position where its outer end coincideswith the circular marking |9 on the outer portion of the dial so thatwhen the hour hand I-I1 shall have moved to a position indicative oftwelve thirty ocloclf., the stud 38 of the member 26 will ride over saidelement, and in doing so, the member 26 will be rocked against theaction of the spring 33. In consequence thereof, motion will be impartedto the shaft 3| to project the pin 29 to the position shown in Figure 6.The pin 23 is thus forced against the leaf spring 95, and the oifset end3l! of said spring is brought to bear against the lug 92 of the latchingmember 89, which, in turn, moves the latter against the normal influenceof the spring |88. In operative synchronism with the aforestatedmovement of the member 26, the cam wheel 43 will have rotated to theposition where its adjacent lobe 53 will have left the edge 98 of thearm 38, allowing the free end of the arm |53 to enter the adjacent space54 and the entire lever assembly 51 to tilt by virtue of the action ofthe spring 51a.. In so doing, the foot 19 of the long arm 69 will bepresented against the latching stub 1| with sufcient force to throw sameout of the notch 8| in the hammer arm 83. Concurrently with thisactuation the branch 15 of the latching arm will be retracted from thenotch 15, (see Figure l0) in the aforementioned disk 11, at which timethe alarm spring 3B will function to render the alarm mechanismoperative for a sounding of the bell throughout a period of timerepresented by a complete revolution of the disk 11. When the pin i8! ofdisk 11 strikes the arm |92, following withdrawal of branch 15 fro-mnotch 15, the lug |95 is forced against the cam surface |91, asillustrated in Figure l0, and the arm 6| thereby rocked in a directionto causeI the pin 5] to ride over the surface |59 and seat behind theshoulder 59 oi arm 58. This forces the entire assembly 51 to move to aposition where the foot 18 will be slightly elevated above the stub 1|,thus allowing the branch 15 to again enter the notch 15 and latch thehammer arm as soon as the branch 15 re-enters the notch 1S or when thedisk 11 makes a complete revolution. Assuming that the pin i9| has actedupon the lug |93 as above stated, the assembly 51 will of course assumethe position shown in Figure ll and the spring 51a now functions to holdthe shoulder 59 against the pin 60 of the arm 6l, whereby to prevent thelatter from moving under the urging action of the spring 34. With theseveral parts inthe positions just described, it is to be understoodthat the latching member` SQ will be entirely released from the arm 6l.The hook 9i of the latching member Q9 is curved along its edge 59 for apurpose to be explained presently. During normal continuation of theclockwise movement of the cam e3, the peripheral edge of the nextsuccessive lobe 53 will gradually wipe against the cam surface of theaforesaid arm E8, gradually tilting the entire lever assembly in acounterclockwise direction, thus causing the shoulder of the arm 58 toleave the pin and allowing the arm 6l to return tol the position shownin Figure 9 ready for the neXt actuation of latching member 8S.Simultaneously therewith, the arm 6l rides over the curved edge H39 ofthe latching member 89 until it shall have again assumed itspositionvshown in Figure 5. It is to be borne in mind that stud 36having left element been allowed to retract by Ywithdrawal of pin 29 aswill be clearly understood upon reference to Figures 5 and 6. Assumingnow that the ele-V ment i@ between the said hours of twelve and oneoclock has been returned to its unset or innermost position in its dialslot id, and that all of the remaining 'elements have been likewiseadjusted, it manifestly follows that the cam i3 may freely operate andthe peripheral edges of its respective lobes moved across or against theedge @il of the arm 58 without causing a tripping or releasing of thealarm mechanism. During this action of the said cam the lever assembly5l will merely oscllate iirst in one direction as will be compelled bythe action of the lobes in their successive engagement against the arm68 and then in an opposite direction as will be compelled by the actionof the spring 51a. The construction of the'organization is such thatwhen all of the elements occupy inactive positions or when none of themlie in the path of either of the studs 36, 3'?, the device may beemployed to satisfy the requirements of an ordinary clock. The minutesindicator 48, from the fact that same is driven in operative synchronismwith the hour hand, makes one complete revolution to one-twelfth of arevolution of the hour hand H1. It is to be understood that I am not tobe limited in this respect, any more than I care to be conned to theprovision oi` means on the dial il for allowing merely four specincactuations to be set up inA the alarm mechanism. I have elected thespecic arrangement simply because of the one particular use to which theinvention may be put.

Next assume that it is desired to cause thel alarm to sound first at onethirty oclock and then at one forty-five oclock. It is simply waybetween the hours of one and two, and stud 3l will engage the element .ein like manner asY before described and the alarm mechanism will beplaced in operation. By the time the next succeeding lobe shall havecome into operative action, the stud 35 will have been acted l5, thespring 95 has.

upon and the alarm mechanism-will be tripped at one forty-five oclock. YA

When the element it on the hour ofV three is moved to the extreme outerposition (Figure l) the pin 3@ will engage, therewith and the stud 3Swill engage said element and the alarm will be sounded.

I show twenty-four of the elements I6 and each thereof functions in thesame manner so that the kalarm may sound (l)- onV any hour; (2) fteenminutes after the hour; (3) thirty minutes after the hour, and (4)forty-veminutes afterthe hour. I have'elected to do this merely for thelreason that the majority of radio programs are for the durations withinthe range of times herein provided for. v On reference to Figure 9, itwill be observed that the free end of arm 63 rests against the face 55of one of the lobes e3 of Ycam 3, at which time the edge of arm 5l whichconfronts the shoulder t3 of latch 89 will be slightly spaced aparttherefrom, (see Figure 5). This is to reduce the friction between thesepart-s during movement of Ythe latch to a released position as shown inFigure 6, at which time the free end of arm $8 will drop into Vtheconfronting dwell of the cam to eect a sounding of the alarm. It will beappreciated that in order to further relieve the time train of loads,the alarm train is, by virtue of the arrangement herein f disclosed,wholly relied upon to return the lever assembly to a position where thefoot lever 7i! will clear the stud 'H after the alarm is sounded. vInorder that one may readily reconcile the terms employed in the claimswith like terms employed in the body portion of this description, theterm clock wor M shall mean the entire mechanism of the conventionalclock Y herein shown; the term "alarm mechanism shall include all of theparts ordinarily employed in an alarm clock plus those extra parts whichI have herein fully disclosed and specifically referred to; the hourhand operating means shall include the intermeshing gear pinions 2i? and2l; the tripping means shall inmeans shall include the entireorganization of elements. it, and the means for causing periodilcalactuations of the tripping means and hence the alarm mechanism shallinclude the spring es, the pm 2e and the arm 2t and its adjuncts, and itis to be borne in mind that the synchronized operations herein referredto are in part due to the provision of the cam i3 on the hour handoperating shaft of the clock works.

The means for stopping operationv of thel alarm mechanism at theexpiration of .a Xed time shall, ofcourse, include the disk 'il and thecoacting branch l5 of the member l2, the notch 'i6 of the disk actingcam-like to force said branch out of the notch and allow for suchmovement of the stub ll as would be obviously required to free thelatter from the notch Si in the hammer arm 83, and to hold same in thiscondition until the disk shall have made a complete revolution. Whenthis shall have been accomplished, the alarm mechanism will cease tooperate. During this operation, the pin lill Will engage the arm 13a andthe lug IDB will be forced against the cam edge IM of the rocker E2,thus moving said rocker and causing the pin 6D thereof to ride over theinclined face lei) and nally come to rest behind the shoulder 5s. Indoing so, the foot 'la of the arm E9 will be slightly raised away fromthe stub ll and to a position above the notch 8|, Where it cannotprevent the stub from re-entering said notch, the disk 'il havin nowmade one complete revolution.
